The first printable magnetic sensor relying on the giant magnetoresistance effect (GMR) is demonstrated. It is prepared in the form of magneto‐sensitive inks adherent to any kind of arbitrarily shaped surface. The fabricated sensor exhibits a room‐temperature GMR of up to 8% showing great potential for contactless switching in hybrid electronic circuits (discrete semiconductor and printable elements)...
The first printable magnetic sensor that relies on the giant magnetoresistance effect (GMR) is fabricated. The magnetic ink can be painted on virtually any substrate such as paper, polymers, ceramics, and glass and exhibits a room‐temperature GMR of up to 8%. The functionality of a magnetic switch printed on a postcard paves the way for interactive and fully printable electronics. Further details...
